Visual Acuity Charts

8

To help you to measure early symptoms of nearsightedness or myopia, this app reassembles Snellen Chart (Traditional, ETDRS, HOTV), Tumbling E Chart and Landolt C Chart traditionally in print, with randomly generated optotypes according to the test distance in metric units or imperial units.

Supported Charts:
1. Snellen Chart, with C, D, E, F, H, K, N, P, R, U V and Z, as defined in BS 4274-1:2003
2. Tumbling E Chart
3. Landolt C Chart
4. ETDRS Chart, with C, D, H, K, N, O, R, S, V, and Z
5. HOTV Chart
6. ETDRS European-wide Chart, with H, K, O, E, P, X, B, T, M and A
7. LEA Symbols for preschool-age children
8. LEA Numbers

Scenarios:
1. "Doctor" and "Patient".
2. Self-diagnosis with a mirror.
3. Self-diagnosis within arm's reach

Modes:
1. Autoplay
2. Traditional

Predefined Test Distances:
* 6, 5, 4, 3, and 2 meters
* 20, 15, 12, 10, 6 feet

And an arm's reach distance may be defined in Settings.

Voice Hint is available for a "doctor" wearing a headphone when observing the responses from the "patient".

Remarks:
While this app may replace Snellen Chart, E-Chart, C-Chart, ETDRS Charts and HOTV Chart in print, it cannot replace doctors and optometrists who would carry out comprehensive tests for your eyes. While generally you are not going to visit an optometrist monthly, however, you can test your visual acuity frequently with this app. For example, if you have young children to take care of, you may test their visual acuity monthly, fortnightly or weekly, so you can take preventive measures early to prevent their visual acuity from getting worse.
